Hi,
I have solved elasticity problem in the cartesian coordinate system, Is there any simple way to get stresses in the cylindrical coordinate system in FEniCS available or any hint how to do this.
Thanks
conversion formula:
\sigma_r = \sigma_x cos^theta + \sigma_y sin^theta + 2 \sigma_xy sin(theta) cos(theta)
\sigma_theta = \sigma_x sin^theta + \sigma_y cos^theta - 2 \sigma_xy sin(theta) cos(theta)
\sigma_z = \sigma_z
